First check on the Nvidia site if you have the latest driver installed.
Then check if Windows update updated drivers. If it did, do a driver rollback and tell Windows update to NEVER update drivers (that's a group policy item or a registry edit).
If no luck (latest Nvidia drivers and nothing changed in Windows drivers) contact Nvidia and ask when they will have a compatible driver for you.
I run 6 monitors and have two NVIDIA Geforce 210 along with the integrated graphics card. I just did a windows 10 update and now one of the cards is not working and device manager tells me "This device cannot find enough free resources that it can use. (Code 12)". Everything working perfectly right before the update.
Any help greatly appreciated.
